Background Gait initiation is a major motor problem for patients with Parkinson's disease (PD). To understand the gait initiation in patients with PD, fluctuation on the first three steps of initiation was examined Methods Force distribution measurement platform was used to record gait initiation in 10 patients with PD and healthy participants. Step length, step time and step width, as well as its coefficient of variation (CV) were investigated Results The findings demonstrated significant main effect of group on step length ( p < 0.001), step time ( p = 0.034) and step width ( p = 0.002), significant main effect of step on step time ( p < 0.001) and step width ( p < 0.001). No interaction between group and step ( p > 0.05) was found on the variables. Compared with healthy participants, patients with PD showed significantly shorter step length in the first ( p < 0.001), second ( p = 0.001) and third (p = 0.001) steps and longer step time in the second step ( p < 0.001). No difference in CV ( p > 0.05) of the variables between groups comparison. Both groups had significant longer step time in the first step compared with the second step (PD, p < 0.001; healthy participants, p < 0.001) and the third steps (PD, p < 0.001; healthy participants, p < 0.001). They demonstrated significant wider step width in the first step when compared with the second step (PD, p = 0.043; healthy participants, p < 0.001) and the third steps (PD, p = 0.002; healthy participants, p < 0.001). Conclusion Patients with PD showed shorter step length of all steps, longer step time in the second step and similar step width when compared with healthy participants. Among the three steps, both groups demonstrated longer step time and wider step width in the first step when compared with other two step. Copyright © 2013 John Wiley & Sons, Ltd.
